To all whom z't may concern.'

Be it known that I, LouisLANE, acitizen vof the UnitedStates of America, and a resident of Habana, Cuba, have' invented a new yand Improved Sash-Gear Balance, of which the following is a. description. 4

My invention relates to balanced sliding sashes having gearliconnectlons therebetween so that a movement of one sash will impart at the retarding corneiilthe' result being a sticking of the sash or jamming of the sash in the guide-way. My invention provides a balance Vgearing so arranged that 'when properly adjusted it will not bey possible for one sashside' to'advanceahead andthe consequent kbinding and stickinglof the sash isf "'thereby'p-revented. "The nature of the invention' and its distinguishing features andI characteristics will --fclearly appear as the descriptionproceeds.

Reference is to be had to the accompanying drawings forming a part of this specilication, it being understood that the drawings are merely illustrative of some examples of the invention.

Figure 1 is a.partly sectional elevation, the View being indicated by the line 1 1,

re 2; 4igure 2 is a horizontal section on the line 2 2, Figure 1;

Figure 3 is a detail in vertical section as indicated by the line 3 3, Figure 2;

Figure 4 is a transverse vertical section as indicated by the line 4 4, Figure 1;

Figure 5 is a detail in side elevation of a modiied gearing;

Figure 6 is a section on line 6 6, Figure 5;

Figure 7 is a sectional plan` View showing a modification of the manner of forming the racks on the sashes.

Referring at first more particularly to Figures 1 to 4,

the numeral 10 designates generally a window formed in. a-cement wall for example. 11 `indicates theA inner and outer sashes yand 12 indicates sheet -metal` window jambA strip-s applied to the main jambs ofthe.' window'and here Shown as of angle shape in cross section. TheA strips 12 may vbe suitablyanchored in' place as at 13.

In lateral recesses ofthe window frame `10 adjacent the level of the meetingfrails ofV the sashes '11 are provided gear boxes designated generally` by the numeral 14 in `which are U-shaped frame-elements 15 that may be secured as by screws 14""L1tov each box-or casing 14. The ramemembers 15A have spaced sides and are disposed-vertically in the plane ofthe window so that the opensides of Said elements 15; of ther opposite posed toward each other.

The free edges 'of the sides of the frame elements 15 are secured4A to anged lvertical U-shaped jambstrips 16 as vby screws-17.

jambs arefdis- The numeral 18 indicates'Z-shaped stopsdisposed against the Vflangesl of'jamb strips'l, outside of the sashes 11, and'l9 indicates the parting' stripsY appliedr'tor'the "faces of thev jamb facings 16.

Turning in the'sides of each `frame 15 are upper yand lower shafts' 22 the oneshaftex tending at-'oneend beyond said frame. and the other `shaft 22 extending at its opposite end beyond'saidframe 15. The extending ends Vof the shafts'22have Vpinions 23; fixed thereon and on said shafts within each frame y15 are intermeshing idler pinions 24, thereby gearing up one shaft 22 with the other so that the one shaft will vrespond to the' turning movement of the other. 'I he inner sash 11 has a rack 25 meshing with one pinion 23 and the outer sash 11 has a similar `rack 25 meshing with the other of said pingive the rack teeth the required width for A eective engagement with the pinion 28.

the described arrangement it will beVK v:Withttbe rack teeth 25 of the channel mem- `'bersw26` of the sashes 11. Said pinions23a f are fast on shafts22a lturning in the boxing` W14". fand side frame members latL in ysaid boXingbetWeen which is a U-shaped .frame member 15b securedto the members [153 by screws :30.V On thefshafts 22@ also-are bevi VVeled pinions 24a with which meshes an intermediate "beveled pinion 24U on a stud shaft^24 turning yin the iframe member 15b :"a'n'dfin a reinforcebar 15c applied to said U=shaped member 15b.

In Figure 7 the gearing is adapted to a wooden sash 11b and a Wood Window frame l'10"for which purpose Ithe sasheshave vertical c'ha`nnels'11c in the fsideedges in Which- Achannels lare iitted rack'bars 25C engaging the pinions 28h. The boxing 14 previously idescribedhas secured thereto the U-shaped vtrarne element '15 by'a screw 14a as in VFigyure Y1. T'heipinions23b are on shafts 22b turnin'g'inf'the framel 15 and in the boi'ring 14.` vW'iththis form ofthe invention inter- *meshing idler" pinions i240 on `the respective f shafts`22b are employed substantially as in the first-described construction.

'II would state in conclusionthatrwhile the illustrated examples constitute practical embodiments of my invention, I do not.' limit my-self st'rictly :to the [exactv details herein 'illustrated since manifestly7 the fsame can be "considerably fvaried 'without departure from the spirit of the invention as dened in the y appended claims.

Having thus described my invention, I claim:
